How to make a checkbox "Read-Only"

[Glenn269]

I have 2 checkboxes in two separate areas of my PDF Form and when the first checkbox (named CheckBoxQ1.4) is checked the second checkbox is also checked (also named CheckBoxQ1.4, because I want both checkboxes checked when the first one is checked by the user).  But I want it so that the second checkbox cannot be checked/unchecked (read-only), so the only way it can be checked is by checking the first checkbox.

I'm not sure if that sounds confusing or not?!  Any ideas on how to make the second checkbox so that the user cannot check/uncheck it?

You can't do that if they have the same name. You need to rename the second field and use a script to set its value to be the same as the first one.
